Since 1967, KOSO Kent Introl have built a reputation on providing high-performance choke and control valves to perform in some of the most severe service conditions throughout the world. Their products can be found in almost every major Oil & Gas producing region, and are used across a wide range of applications, including Oil & Gas, petrochemical, power and utilities industries.
The KOSO Kent Introl team have the knowledge and experience to engineer solutions for their own product as well as for other manufacturer’s valves. Backed by their engineering quality, customer focus and fast technical responses, KOSO Kent Introl can create technical engineered solutions that benefit not only the valve but the efficiency of the whole application.
KOSO Kent Introl is part of the KOSO Group of companies. Whilst they retain a great deal of independence, the group structure gives them buying power, influence and stability of being part of a large global entity.
Engineered to meet a wide range of applications and service conditions, KOSO Kent Introl’s control valve range includes the following products:
Series 1200 (globe) & 7200 (angle) are the high-performance cage-guided control valves.
Series 10 control valves are the single-seated heavy top guided designs.
Series 20 control valves are a double-seated design of control valve that inherently have a balanced trim.
Series 30 are 3-way control valves for mixing or diverting applications.
Series 60 range Rotrol butterfly control valve for standard and severe service applications.
Their control valves are designed to specifically meet the actual process conditions in each application, whether that be in the Oil & Gas or power industries. Refined by KOSO Kent Introl’s engineers, their control valves can be fitted with specific trims to manage problems such as high velocities, noise, cavitation, flashing and erosion. The control valves can also be used in conjunction with a number of different actuator options.
Typical Design Features:
Modular construction design available with a range of different end connections and styles.
Large variation of trim designs from single stage drilled cage to multiple stage velocity control VeCTor™/low noise/anti-cavitation trim designs.
Inherently characterised trim offered in equal percentage, modified Eq%, linear and quick open.
Balanced or unbalanced plug designs.
All trim components removable from the top for ease of maintenance and quick replacement.
Clamped cage for positive guiding on severe service applications.
Large range of CVs per body size allowing for large changes in process conditions.
Low emission packings i.e. (ISO 15878).
Surface Choke Valves:
KOSO Kent Introl’s technically advanced Series 73 range of choke valves has been effectively used in the Oil & Gas industry since 1975. The range offers a wide choice of different materials and trim options making it flexible to meet the needs of even very specific and challenging projects. All Series 73 choke valves use a low-pressure recovery, high friction trim design. This protects the vital pressure-containing boundaries of the valve against damage from erosion and cavitation. Dependent on the needs of your project, the Series 73 range can work with single or multi-stage trims and the proven KOSO VeCTor™ velocity control labyrinth disk stack design.
Typical Design Features:
Choke body materials can be of forged, Hot Isostatic Pressing (HIPped) or cast construction.
Numerous trim designs from single stage high capacity to multi stage velocity control VeCTor™/low noise/anti cavitation.
Premium grade (solid) tungsten carbide throttling/control elements.
Non-collapsible trim design option (100 joules and 1320 joules impact tested).
Various trim sizes can be used, in different choke body sizes, to ideally suit the process parameters.
Bi-directional flow option.
Special LCV trim design to accommodate high sand concentration.
Special choke designs with API 6A pressure inlet & body design with ASME rated outlet connection.
A wide range of actuator options are available.
Severe Service Valves
KOSO Kent Introl have developed a range of advanced, high-quality severe service valve solutions for every type of problematic application, from high-pressure, high-temperature environments to sub-zero temperatures. Their valves are designed to combat the effects of cavitation, flashing, erosion, contaminated fluids, corrosion, high velocity, vibration, noise and energy dissipation.
In addition to this, KOSO Kent Introl has the proven KOSO VeCTor™ velocity control labyrinth disk stack design in it's product portfolio. The VeCTor™ trim gives you the option to source a high-performance trim for the control of extremely high velocity conditions that would potentially damage the control valve and downstream pipework if the velocity is not managed appropriately.
Typical Severe Service Applications:
Anti Surge – Compressor Recycle.
Pipeline Surge Relief Control.
Centrifugal Pump Minimum Flow Recirculation.
Fire Water Deluge System.
Vent to Flare.
Separator Level Control.
Boiler Feed Water.
High Pressure High Temperature (HPHT).
KOSO Kent Introl maintain the highest standards of quality throughout design, production and customer service. Their organised and documented Quality Management System (QMS) is fully implemented at all levels in their organisation. Within the QMS is a well-established programme for auditing both their supply chain and internal processes on a frequent basis.
